Printed circuit board design is always a balancing act. We use vias anyway, but in a different way. Wrapping the bus in a full metal sheath on the outer layer and riveting the edge of the ground plane to the inner layer ground is usually sufficient to meet EMI specifications involving short digital traces.

To solve the inner layer short circuit problem of PCB multilayer circuit board, first of all, the main process factors that cause inner layer short circuit must be clarified, and then corresponding process countermeasures can be taken in a targeted manner.

PCB For power supply design, it is necessary to perform a good PCB layout and plan an efficient power distribution network. It is necessary to ensure that noisy digital circuit supplies are separated from critical analog circuit supplies and circuitry.

A software design program that performs signal and board analysis during PCB design can help you properly select board materials, trace routing, via types, and other DFM specifications, thereby reducing manufacturing overhead. Manufacturing overhead depends largely on production levels.

We hope to help you get your PCB manufacturing goals right. A good company/manufacturer in PCSPCB that provides prototyping services will have a dedicated team and department to execute your project and ensure quality and results according to your needs.

In the PCB drilling process, it is necessary to mainly control the following quality problems that may occur: porosity, leakage, displacement, mis-drilling, non-penetration, hole damage, partial waste, burrowing, and plugging.

HDI PCB are circuit boards designed to maximize surface component density, provide a breakout solution for ICs with a large number of closely spaced pins or pads, and/or propagate high frequency signals. The aim is to provide greater functionality in a smaller package.

Component packaging plays a role in mounting, fixing, sealing, protecting chips and enhancing electrical and thermal performance. The contacts on the chip are connected to the pins of the package shell with wires, and these pins are connected with other devices through the wires on the printed circuit board, so as to realize the connection between the internal chip and the external circuit.

PCB manufacturers have their own set of standard through-hole sizes to choose from when drilling, but they can usually use any standard drill size.

The development prospects of PCB and several common mistakes? Recognizing these errors before they affect the overall functionality of the board is a great way to avoid costly production delays.

Process requirements of PCB manufacturers. Including the basic parameter requirements such as the number of PCB layers, thickness, aperture, minimum line width and line spacing, copper thickness, etc., as well as special requirements such as sheet type, surface treatment, and special processing.

It is time to pay attention to some details in the detection of PCB boards, so as to be more prepared to ensure product quality. When testing PCB boards, we should pay attention to the following nine common senses.

Each of these vias needs to be managed in order to use it properly to ensure optimal board performance and error-free manufacturability. Let's take a closer look at the need to manage high-density vias in PCB design and how to do it.

Solder mask (SM) of PCB, solder mask is usually printed after the production of PCB circuit, because the color of ink usually used for circuit boards is green, accounting for more than 90% of the PCB industry, so solder mask is also called green oil.

Five skills that PCB design engineers must master: skilled use of PCB design software, basic English ability, familiarity with devices, reading circuit schematics, understanding key signals, a certain understanding of SI/PI knowledge, and EMC/EMI Knowledge has a deep understanding.

There are many technical specifications related to wiring line width, wiring stackup, schematic diagram and so on in PCB design. Ten small suggestions for PCB component placement can guide electronic beginners to smoothly walk through the initial stage of electronic design.
